Myf'inve'ntion relates more particularly to a one piece paper top orbottom formed into an oblong or round cup shape, which is adapted to beinserted into and form the end of a paper shell or tube to which said'cup shaped end is suitably glued or otherwise adhesively sealed and`given pressure.

The object of my invention is to provide a simple, strong, durable andeconomical top or bottom for a paper container.

My invention consists in a one piece paper or pulp head orl end or topor bottom of a paper or pulp container centrally dished with aprojecting bead or rim and having its ed e inturned upon itself to forma lap.

y invention also consists in the details of construction and in theparts and combination and arrangement of parts as herein set forth andclaimed.

In the drawings:

Fig. 1 is a vertical section through a cylindrical head forming part ofmy invention;

Fig. 2 is a perspective view partly broken away of an oblong rectangularpaper boX having its top and bottom provided with my novel heads.

Fig. 3 is a perspective view partly broken away of a cylindrical papercontainer embodying my invention;

Fig. 4 is a sectional view of modified form of head;

Fig. 5 is a sectional view of another modication.

In the embodiment of my invention as illustrated and which showspreferred constructions, the body or shell 1 or 1, as the case may be,is formed in any usual and well known manner into theshape shown. Thehead 2 or 2, is preferably dished inwardly to reinforce and strengthenit and to cause the containers when stacked upon each other to rest morefirmly than otherwise. The head is formed with a projecting bead 3 or 3by turning a portion of the head upon itself, and this bead is adaptedto snugly fit and rest upon the end of shell 1 or 1 and if desired, toproject slightly beyond the quae Surface er fsai'dfsheiimagneet ehe deasiredornamentiffinish Therheadf. isaalsefl provided with- 'an integralflanl ef'or: 4t' exa? tending fat an angle te4 tl'i'effrnain.yaitoffsaide head1l and' -ritsf edgel :is intulrnedlupon'iitselfftf forma strengthening and finishing' lap 52"; The f peculiar formation'o'fth'e-fheadeas ithuis described, :isfobtain'ed byf meansro'fasuitab'lef'f diesf andi# t'o'olsgvnet'V formi-ngir a part ofgthe presentinvention. The head, when formed as illustrated and described, producesa very strong structure which, when its flanged and beaded surfaceabutting the shell, is glued or otherwise adhesively secured thereto,forms a very substantial container.

These containers are particularly adapted for use as receptacles forpowders, liquids and solids. When so used, one head may be secured inposition and glued or otherwise secured to the shell, leaving the otherend open'for receiving the contents. AWhen the container has beenfilled, the other head may be inserted and the container is then readyrforuse. If it is desired that the container be completely sealed afterreceiving the contents, the flanged and beaded surface which engages theshell, may be coated with adhesive material and inserted. If desired,suit# able pressure may be applied to the outer surface of the shellopposite flange4 or4 of the head to cause the head and shell to becomevery firmly united by the adhesive. Where very small containers are usedor where especially heavy-and strong paper is em lo ed, the dish 2 or 2may be omitted anc t e surface of the head formed flat. Likewise, whenadded strength is not required, the lap 5 -or 5 may be omitted as Vshownin Fig. 5. The word paper as used in the specification and claimsincludes paste board, fibre and the like.

' It will be apparent that my invention is capable 0f some modificationwithout material departure from its scope orl spirit, as shown by theexamples given. The shape ofthe container may be cylindrical orrectangular as shown or may be octagonal or any other desired shape, inwhich case the'shape of the head is modified to adapt itself to theshell, but the novel features ofI my invention are the same in any formof shell in which it may be used. y

What I claim as new.and desire to secure by Letters Patent is:

1. An article of manufacture comprising a straight paper tube or shellhaving its head or end formed from a single piece of paper dished orstamped and crimped at its closed end to form a laterally projectingbead or rim and having its open end inturned upon itself to form areinforcing and finishing lap, substantialy as set forth and for thepurposes specified.

2. A paper head for paper containers having a laterally extendingintegrally formed bead projecting beyond the circumference of the tube,a transversely extending integrally formed flange, and a reinforcing andfinishinO' lap inturned upon said flange, substantia ly as set forth andfor the purposes specified.

3. A container comprising a paper tube or shell having its head or endformed from a single piece of paper dished or stamped and crimped at itsclosed end to form an elongated projecting bead or rim, said head havingits open end inturned upon itself to form a lap, said head and shellbeing firmly bound together by an adhesive interposed therebetween and apressure applied upon the surface of said shell adjacent the flange andbead of said head, substantially as set forth and for the purposesspecified. 4f. An article of manufacture comprising a paper tube orshell having its head or end formed of a separate member from a singlepiece of paper dished or stamped inwardly and crimped at its closed endto form a straight bead or projecting rim and having its open endinturned upon itself to form a reinforcing and finishing lap,substantially as set forth and for the pur oses s ecilied.
